Q.Tumbler
I have a rotating tumbler, about five feet long, opens from the side and has a one inch pipe with one eight holes in it running from end to end in the middle and material covers the pipe. Is the material getting enough air or do I need to drill more holes in the tumbler? Is it possible to get more heat in the winter months? Thank you.

A two inch pipe with 1cm holes every inch is recommended. If you can increase the diameter of the holes, your composting p rocess might speed up. If not, the process will still occur. Don't let your compost dry out, it needs to be moist, not wet. To make compost hotter, adding manure is the quick fix.
